Machine for cooling and stacking flat printed articles

ABSTRACT

A machine for cooling and stacking flat printed articles. The articles issue from a printing press in streams which are caused to diverge. The articles are arranged in shingle-fashion and projected into brush belt conveyors where the articles are spaced and cooling air is blown around the articles. The articles are advanced upwardly by the brush belt conveyors. The brush belt conveyors advance to downwardly moving portions to invert the articles, and the inverted articles are stacked at a plurality of levels. Skids are advanced to the levels to position opposite the stacks, and the stacks are advanced onto the skids.

1. In a machine for loading articles onto a skid, skid handling apparatus which comprises a skid lift, means for supporting skids at a skid loading level, means for advancing the skids along the skid loading level toward the skid lift, means on the skid lift for drawing one of the skids onto the skid lift at the skid loading level, the means for drawing the skid onto the skid lift being constructed to discharge the skid at a stack loading level, means for advancing the skid at the stack loading level to a stack receiving station, means at the stack receiving station for advancing stacks of articles onto the skid, the means for advancing stacks of articles onto the skid including a transfer tabLe having elongated transfer belt means, the transfer table being raisable and lowerable at the stack receiving station between a raised position in which the transfer belt means extends through slot means in the skid and a lowered position free of the skid, means for advancing a stack of articles onto the transfer belt means when the transfer table is in raised position, and means for advancing the transfer belt means to advance the stack above the skid, the stack being deposited on the skid when the transfer table is lowered.
 2. A machine as in claim 1 wherein there is a light beam extending crosswise of the path of skid advance ahead of the stack receiving station, means for stopping the skid advancing means when the skid is at a first skid position at the stack receiving station in which the skid is in the light beam to break the light beam, means for advancing the skid advancing means to advance the skid to a second position at the stack receiving station in which the skid is free of the light beam when a first row of stacks of articles has been received thereon at the first position, and means controlled by the light beam for advancing another skid to the light beam when the first skid is at the second position.
 3. A machine as in claim 2 wherein there is a second skid advancing means at the stack loading level for advancing the skid away from the stack receiving station when a second row of stacks has been received on the skid while at the second position.
